Background: The aim of this study was to determine the outcomes of primary bypass graft surgery (BGS) compared to BGS after failed angioplasty (PTA). Patients and methods: Between January 2007 and January 2014, we performed 136 BGSs exclusively for the treatment of critical limb ischaemia. Two cohorts were identified: 1) primary BGS (n = 102; group I), and 2) BGS after prior PTA (n = 34; group II). Data were analysed retrospectively and the primary endpoints were the rates of secondary patency, amputation-free survival, freedom from major adverse outcomes (graft occlusion, amputation, or death), and overall survival, which were assessed with the Kaplan-Meier method. Results: Both groups were comparable with a predominance of Rutherford\u2019s category 5 ischaemic lesions (73.3 %). Most patients had extensive TASC D athe-rosclerotic disease (83.6 %), and the main conduit was the greater saphenous vein (58.1 %). The mean follow-up time was 36.2 months. The 3-year secondary patency rates were better for group I (64.3 % vs 49.6 %; P = 0.04). During the same period, the amputation-free survival rates were similar between the groups (77.4 % vs 74.5 %; P = 0.59). For multivariate Cox regression analysis, BGS after prior PTA was the only factor associated with re-intervention for limb salvage (hazard ratio = 2.39; CI 95 % = 1.19 - 4.80; P = 0.02). At the 3-year point, there were no differences in the overall survival rates (72.6 % vs 70 %; P = 0.97), but the proportion of patients without adverse outcomes was higher in group I (37.3 % vs 13.4 %; P = 0.007). Conclusions: Although secondary patency was better after primary BGS, the amputation-free and overall survival rates support the use of BGS after prior PTA. <\/jats:p>","DOI":"10.1024\/0301-1526\/a000542","type":"journal-article","created":{"date-parts":[[2016,7,18]],"date-time":"2016-07-18T14:20:35Z","timestamp":1468851635000},"page":"305-310","source":"Crossref","is-referenced-by-count":4,"title":["Results of bypass graft surgery after prior angioplasty in critical limb ischaemia treatment"],"prefix":"10.1024","volume":"45","author":[{"given":"Marcus Vin\u00edcius Martins","family":"Cury","sequence":"first","affiliation":[{"name":"Department of Vascular and Endovascular Surgery, Hospital do Servidor P\u00fablico Estadual de S\u00e3o Paulo - HSPE, S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francisco Cardoso","family":"Brochado-Neto","sequence":"additional","affiliation":[{"name":"Department of Vascular and Endovascular Surgery, Hospital do Servidor P\u00fablico Estadual de S\u00e3o Paulo - HSPE, S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcelo Fernando","family":"Matielo","sequence":"additional","affiliation":[{"name":"Department of Vascular and Endovascular Surgery, Hospital do Servidor P\u00fablico Estadual de S\u00e3o Paulo - HSPE, S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rafael","family":"de Athayde Soares","sequence":"additional","affiliation":[{"name":"Department of Vascular and Endovascular Surgery, Hospital do Servidor P\u00fablico Estadual de S\u00e3o Paulo - HSPE, S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna Karina Paiva","family":"Sarpe","sequence":"additional","affiliation":[{"name":"Department of Vascular and Endovascular Surgery, Hospital do Servidor P\u00fablico Estadual de S\u00e3o Paulo - HSPE, S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roberto","family":"Sacilotto","sequence":"additional","affiliation":[{"name":"Department of Vascular and Endovascular Surgery, Hospital do Servidor P\u00fablico Estadual de S\u00e3o Paulo - HSPE, S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"101","container-title":["Vasa"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/econtent.hogrefe.com\/doi\/pdf\/10.1024\/0301-1526\/a000542","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,3,17]],"date-time":"2021-03-17T00:49:32Z","timestamp":1615942172000},"score":1,"resource":{"primary":{"URL":"https:\/\/econtent.hogrefe.com\/doi\/10.1024\/0301-1526\/a000542"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,7]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2016,7]]}},"alternative-id":["10.1024\/0301-1526\/a000542"],"URL":"https:\/\/doi.org\/10.1024\/0301-1526\/a000542","relation":{},"ISSN":["0301-1526","1664-2872"],"issn-type":[{"value":"0301-1526","type":"print"},{"value":"1664-2872","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,7]]}}}
